And as a warning, the good ole British motorcycle industry used to have a single Bowden cable connecting the twist grip to the carburettor slide on the engine so that when you twisted the handlebar grip back towards you, the bike accelerated and by allowing the grip to twist the other way, assisted by a return spring, the revs and the bike slowed down. As any proper motorcyclist will tell you, in their infinite wisdom, the Japanese really screwed things up by putting the kickstart (?) and the brake pedals on the wrong side of the bike for us imperialists and as a belt and braces, on one machine, besides a return spring on the shaft that coupled twin carbs, they had added another cable to the mix that together with the spring pulled the carb slide shut via a pulley. Velly clever these Orientals, so when out one day, miles from home, the cable that opens the throttle breaks. Oh, woe, no tools, (don't need those cos these bikes don't go wrong). Quick think, return spring still works and with a bit of fiddling, the remaining cable can be fed round opposite side of pulley and wahoo, we have twist operated throttle and spring return.
Only difference is that to accelerate, you need to turn the twist grip
away from you and
towards you to slow down.
This is not intuitive and created some exciting moments in teatime traffic.
